Application filed June 30, 1922, Serial No. 572,005, and in Germany June 80,- 1 921 This invention relates in general to em- I broide'ry machines and in particular to'shuttle embroidery machines intended for working a beaded thread. The working of such a thread is connected with difficulties, such as the following. The bead-carrying portions of the thread arerendered too stiff or practically rigid by the beads; the horizontal portions of the thread are weighted too much by the beads; and, finally, thebead-carrymg portions are likely to oscillate during-the embroidering procedure. These drawbacks, es-v pecially if'they occur at the same time, or co-act respectively, impair the proper feed of the thread, as well as of the beads, and are detrimental also to the formation of the loop. When providing means by which those drawbacks may be overcome, attention must be paid to the fact that the beaded embroidery thread is not completely covered with the beads. There are thread portions without beads because some length of thread is required for the connection with the fabric that is to rec-Eve the beads. .Such a fastening connection is made,'gene'rally, after every second bead. .Owing to'this necessity, the bears are so distributed upon the thread which is wound on abobbin that one beaded thread convolution alternates with one 'or two convolutions having no beads. This be-f ing so, the beads would not come uniformly from the supply bobbin to the embroidering needle if means werenot provided by which they are subdivided into groups of a certain number .of beads so thatalways only one such group is present in th'e neighbourhood i of the embroidery'tools.

Now, the gist-of'the present invention resides in the combination of a mechanism for preliminarily subdividing the beads into groups, as above mentioned, with 'a-mechanisnii'for regulating thatsubdividing, espe-.

cially with aid of a touching member. as laterondescribedyand there is, besides pro vided an elastic thread guide which always holds the thread a little under tension whereby the proper operation of the mecha nisms mentioned is: warranted. In fact, a

certain tension of the embroidery thread is a fundamentalcondition for the lunobjectionable working of the bead supplying means, because the beads glide down on a -tensioned thread by" far easier than on a slack one.

On the other hand, however, the elasti thread guide may give rise to the danger of the thread being drawn back during the rocking motion of the needle whereby the formation of the loops would be disturbed,

if not entirely prevented. That danger is,

however, obviated, also according to the present invention by the provision of means for making the elastic thread guide stationary in the proper moments, especially during the formation of the loops and, if necessary,

also whilst another group of heads is sepadefinite initial position whereby the embroidery thread is given as much freedom as necessary for the formation of the loop.

In order to 'make my invention more clear, I refer .to the accompanying drawings, in which Figure 1 is a side-view of the mechanism for supplying the embroidery thread. Figure 2 is a detached view showing solely the elastic thread guide which. forms a part of that mechanism. Figure 3 is a plan of the parts supported on the shaft 22 of Figure 1, and being drawn on a larger scale. Figure 4 is a vertical longitudinal section through the supporting member for an inclined portion of the beaded embroidery thread, the scale being the same as in Figure 3. Figure 5 is a front view, partly'in vertical axial section, of the means for holding the'supplybobbin for the beaded thread. Figure 6 is a front view of the mechanism for the preliminary :subdividing of the beads. Figure 7 shows a certain mechanism fully dealt with hereinafter. Figure,8 is an illustration similar to Figure 1, showing a modified form-of execution. Figure 9 is a front view of the mechanism for the preliminary subdividing of the beads, in combination with a guidemember, the whole referring to Figure 8. Figure 10 illustrates the manner of action of the touching member;

The embroidery thread a: which comes from the supply bobbin 1 and has beads upon it is guided over the guide member 5 to the wheel 6 by which the preliminary subdividing of the beads into groups, as above mentioned is effected. The objectof the guide member 5 is to prevent lateral 0scillations of the beaded thread because such oscillations would disturb the proper sup-- ply of the thread. To ensure the efiect desired it is recommendable to tilt the otherwise vertical guide member just a little and to arrange the supply bobbin as much nearer the fabric to be embroidered as corre- 'sponds to the degree of tilting. The upper part of the guide-member is then nearer the fabric than is the lower part thereof. The object of the roll 7 suspended from an arm 7 is to hold the beads which are present on the thread securely in the range .of the wheel 6.-

The division wheel '6 is bordered'at both sides by guide disks 6 and 6" which hold the beaded thread securely in the range of thedividing teeth of said wheel'6. This latter is rigidly connected also with two ratchet-- wheels 23 and 23, of which the one is for locking in the one direction and the other for locking in the other direction. The wheel-set 6, 6, 6", 23, 23' sits loosely on the shaft 22 and is pressed by a spring (not shown) against the operating lever "40 which is rigidly connected with said shaft. The lever 40 has aflixed to it a toothed segment 41 which meshes with a cog-wheel 42 aflixed to the operating shaft 43 that extends through the entire length of the machine. The shaft '43 is rocked by suitable means provided on the one side of the machine, and the rocking motion is transmitted to the shaft 22 by the toothed gears 42, 41. The division wheel 6 would partake in the rocking motion .if the ratchet-wheels 23 and 23' did not form checking members. The wheel 23 co-operates with a pawl 44 which prevents the return movement of the division wheel 6 when the shaft 43 is turned in this direction, in consequence of which the wheel 6 can be turned only in steps and only in forward direction. The ratchet-wheel 231co-operates with two pawls46 and 21, of which the first/sits loose- 1y on its supporting pivot and is kept in gear with the wheel 23 either by its own weight, or i by a spring, as long as it is not released by a lever 46' which is secured to a shaft'47 that also extends through the entire length 'of the machine and is also rocked by; means which allow of regulating the extent of this rocking motion, 'as is more fully described herein.- after. The regulation may be such that the angular motion of the wheel 6 is of such an extent as corresponds to the size of the beads ,to be worked. In order to I explain more .clearly the arrangement and manner of operation of the pawl 46, I add that it is sup- 1 ported at the frame of the machine in sucha manner, that it can engage the ratchetwheel 23 so as to check it. A portion of the able along it.,

pawl 46 embraces a bolt provided at the lever 46 whereby the' awl can be lifted off the range of the rate et-wheel when the lever 46 is turned a little in such a direction that' it moves away from the shaft 22.

The pawl 21 which engages the ratchet wheel 23. The fee ing or touching member 14 has at its lower end a plate 31 opposite to which is arranged a counter feeling or touching member 33 located on the needle bar 32. The surfaces of contact of the parts 31 and 33 are so adjusted that the beaded thread coming fromthe elastic thread guide may be carried through between them without being bent or cracked. If, then, beads remain be: tween the parts 31 and 33, the feeling or touching member 14 isthrust back when the v embroidery needle advances, whereby a projection 48 provided on the feeling member 14 gets into the range of'a lever 49. This isrigidly aflixed to the shaft 47 and partakes, thus, in the rocking movements of the same. The effect is that if the pile of beads becomes too high, the touching member 14 ispressed.

down and the pawl 21 is made to engage the ratchet wheel 23. In this case, therefore, this wheel and, thus, the dividing wheel 6 also, cannot rotate even if disengaged from the pawl 46. In order to make the movement of the lever 49' independent of the touching ,member at that moment-in which the pawl 21 engages the ratchet wheel 23, the projection 48' of the touching member is not rigidly connectedw'ith this latter, but displace- It is then drawn upward along the touching member bymeans of a spring (shown in dotted lines between the numerals 50 and 48in Figure 1 until the abutment bolt 50. rovided at theprojection 48' contacts with t e upper end of a slot provided in the member 14.

The shaft 22 which carries the dividing wheel 6 supports also the thread guide 28* which is loosely arranged upon it. This guide has the shape shown in Fig. 2 and has at its outer end a roll 51 over which the.

beaded thread is conducted. At the upper portion of the guide is a curved abutment arm 53 which is engaged at the point 54 by the driver55'that 'is rigidly aflixed to the shaft 43. 4

At each cycle of operations thedriver-55 is so much turned that it disengages the thread guide completely for some time, and then J the handle 52 which forms a part of it, if

the bead thread measea must. again be laid into the roll 51; a

At the point 56 a spring 30 engages the thread guide 28. The other end of that spring is firmly secured by means of a screw 57 to a collar 58 which is rigidly connected with the shaft 22, in consequence of which the preliminary tension of the spring depends upon the motions of the shaft 22. It is, thus, possible to make the tension decrease during the stitching movement of the embroidery needle, and to make it increase during the-return motion wherein resides a specially remarkable feature and advantage of the present invention. The spring 30 thrusts the thread guide constantly upwards, although with varying power: its upward movement is, however, limited because the abutment edge 59 of the curved arm 53 contacts,in the highest position of the thread guide, with the draw bar 60. This bar extends through the entire length of the machine and is axially displaceable in its bearings. There are arranged on it (Fig. 6) for each thread guide 28, a checking disk 61, a collar 62, and a spring 63 which is located between these parts 61 and 62. The spring 63 forces the checking disk 61 away from the collar 62 to the extent permitted by the abutment bolt 64. Between the check disk 61 and a counter bearing66 attached to the machine frame, or one. of a series of small standards 65, the elastic thread guide may at any time be secured in place against move-' ment by an axial displacement of the draw bar 60 by means of the checking disk, which,

however, is effected automatically at every stitch, for instance duringt-heloop formation.

There is provided for the thread guide 28 also an abutment bolt 67 which isengaged by the hobke'dend 68 of the arm 53 if the thread guide. is drawn down too much by the embroidery'thread. The bolt 67 is rotatably supported-in a standard 65, and flat tenedjust over the thread guide iii-"such a.

manner that this guide may be unimpedeuly turned after the bolt has, arrived in the cor-' responding adjusted osition; The bolt is provided, for this purpose, with a small handle 69, but there is also provided a spring 70 located between the part 69 and the standard 65; the purpose of this spring is to hold the abutment bolt automatically in checking position.

In order to'pro'perly support the bead series which is continually kept in store between the pre-dividing wheel 6 and the guide roll 51 during the working of the machine, so that it cannot oscillate, the thread guide 28 is provided with a guide-gutter 72, one end of which forms a thin tongue 73 i that extends between the guide disks 6 and;

6 near to the pre-dividing Wheel 6, whereas the front end or mouth 74 of the gutter is upwardly bent and has a notch. The naked embroidery thread may 'unimpededly pass along at that gutter-mouth 74, Whereas the beads meet at that mouth with a certain, although small, resistance so that they cannot be carried along by the friction of the thread. They pass over the roll 51 only if fresh beads are shoved forward by and from the pie-dividing wheel 6 and the foremost beads are, thereby, pressed beyond the gutterm'outh 74. The effect then is, that a pile of heads is always in the immediate neighbourhood of the roll 51; that is especially important if after a plurality of stitches with beads a somewhat long row of stitches without beads is to bemade, and if, thus,

thread is-to be supplied and, finally, drawn tight, but no beads are to be supplied to it. It might then occur were it not for the notch that all beads between the' pre-dividing wheel 6 and the guide roll 51 would eventually be carried along by the thread friction, so that they accumulate far beyond the members 31 and 33. These latter would then interrupt the further .supply of beads until the accumulated beads are used up. Only then another supply of beads from the wheel 6 could take place, but these beads would accumulate on the thread piece between the wheel 6 and the thread guide roll 51 without passing further behind this latter to the ber 31 and the needle 11 would be used up already previous to completely filling the thread portion in questionwith beads. The result would be wrong stitches, but such a result is prevented by rendering the further supply of the heads a little difficult by means ,4 of the gutter-mouth 74:, as described.

The shaft 22 must be .very thin and it is, 7

therefore, not possible to let it extend through the machine as a continuous piece but it must be composed of bolt-like single peces,,the length of which corresponds to the spacing of the needles, so that a special shaft piece. appertains to each embroidery needle. Owing to this subdivision, there is arranged on each shaft piece only-one prediViding mechanism and the-corresponding thread guide, which parts form a kind of self-contained whole that may be exchanged independently of the other ones, if such an exchange should become necessary by reason of a disturbance of the proper working of the machine, The short shaft pieces 22' are supported by the small standards 65 having lower detachable bearings 75 which permit must be adjustable and the pawl 46 must be releasable by thelever 46' sooner or later corresponding to the size of the beads to be worked. I

There is arranged, for the purpose in view, on the main shaft 80 a cam disk 81 which is located on the power side of the machine and upon which runs the roll 82.

This roll is carried by a. lever 83 carriedin its turn by another lever 85-by means of a bolt 84. The lever 85 is supported on a shaft end 86 which supports also a double lever 87, 88, which is fixedly mounted on said shaft 86, and the arm 87 of which is engaged by a spring 89 so that a lug 90 which forms a rigid projection of the lever 85 is pressed against the abutment screw 91 held by the frame. To the lever arm 88 is hinged a thrust bar 92, the free end of which acts directly upon the lever 93 and, by the mediation of this latter indirectly upon the shaft 47. p

It results from the above that all movements of the lever 85 are positively transmitted to the shaft 47. To attain the effect intended, the regular movements of the roll '82 which are always of the' same extent must, thus, be transmitted'to the lever 85 in an adjustable manner. Thisis effected by v the provision of an adjustable abutment bolt 94 of a lateral arm 83 of the lever 83, that bolt engaging temporarily a lug 95 at every oscillation of the lever 83. The lug 95 is supported on a bolt 96 in the lever and has a foot member97 which engages the hub of the lever 85 whereby it is held in proper position; A spring 98 which is weaker than the spring 89 connects the body of the lug 95 with the lever 83 in such a manner that the roll 82 of this lever is pressed against the cam disk 81. When this disk moves the roll 82 away from the shaft 80, the lever 85 remains at first stationary under the actionof the spring 89 and of the abutment members and 91, whereas the lever 83 turns on its pivot 84 until the abutment 94 contacts with the lug whereby the three parts 83, 85, 95 are practically connected with each other, at least in such a manner, that they behave like a rigid whole. This whole is then turned by the cam disk 81 upon the shaft end 86 contrarily to the pull of the spring 89 whereby the shaft 47 is turned, or adjusted. respectively.

In order that the turning of the lever 85 by the lever 83 may be varied at will, the abutment bolt 94 is threaded and thus adjustable in the arm 83 and is provided with a hand wheel 99., the hub 100 of which has teeth which co-operate with a spring-pressed pin'101 whereby the bolt me. be secured in its adjusted position. Accor ing as the bolt has been more or less screwed forward in the arm' 83, it contacts earlier or later with the lug 95 and turns the lever 85 in a corresponding measure.

The lug 95 is provlded with a bolt 102 located in'a slot 103 of a vertical rod 104 suspended from a lever 106 afiixed to a shaft 107. This shaft may be turned in such a direction that the 'rod 104 is raised and the lug 95 is lifted out of the way of the bolt 94 so that then no motion can be transmitted from the cam disk 81 to the lever 85 and the shaft 47. But'as long as the shaft 107 is not thus turned, the mechanism (Fig. 7) 0pcrates in the manner described. The bolt 102 may then freely move up and down in the slot 103, viz, when the lever 85 is turned.

Concerning the supply of the beaded embroidery thread from the bobbin 1 to the pre-dividing mechanism, it is to be borne in mind that each bead-requires a piece of thread, the length of which' corresponds about to the diameter of a bead, and it is therefore necessary that the beads do not it necessary to arrange all store bobbins in the same height over the pre-dividing mechanism so that the thread is uniformly drawn off from all bobbins. These latter must, therefore, be located side by side, in close proximity, whereby, however, exchanging them is rendered difficult, if they are to'be arranged not'at right angles to the plane of the fabric, but c'o-axially, viz, with consideration to the guiding of the thread by the member 5.

New, in order to facilitate exchanging.

the bobbins, each second bobbin ma be lifted by means which are hereinafter escribed and afford access to each individual bobbin so that each may be easily and convenientl exchanged. The bobbins 1 are hollow. Eac is slipped on .a metallic tube 111 carried by a pin 112 affixed toa lever 113 suspended .-loosely from a shaft 114. The tube 111 is rotatable on the-pin 11 2, together with the bobbin 1, with which it is coupled by a cogwheel 124 and a pin 123 which are more fully dealt with at a subsequent part of this specification. The shaft-embracing upper end of the lever 113 forms an eye 115. L at erally from this eye is a similar eye 116 which is rigidly connected with the other eye by an arm 117. The object of this arrangement is to preventv the lever 113 from shaking on the shaft 114. Between the eyes 115 and 116 upon theshaft 114 is a collar 118 which is connected with the eye 116 by a spring 119 in such a manner that the eye 116 is pressed away from the'collar and, besides, tends to turn upon the shaft 114 together with the lever 113 and the bobbin whereby a rearwardly extending arm 120 of the lever 113 (Fig.1) is made to contact with a rail 121 attached to the frame of the machine.

The collar 118 of each second store or supply bobbin 1 has an upper projection 122 which moves away from the arm 117 if, by a suitable rotary motion of the shaft 114, each second bobbin is turned into the position 1 indicated by the dash-line circle in Fig. 1. The other bobbins remain in their former position by reason of the action of their springs 119 so that every bobbin is easily accessible and may be exchanged, if necessary. There is, of course, always the possibility of a desired bobbin out of the se-- ries having to be removed by hand in order to exchange it for freshone.

The thread is checked in known manner by the following mechanism: Each bobbin 1 is connected by a bolt 123 with a ratchetwheel 124 firmly attached to the tube 111. The teeth of the wheel 124 are engaged by a pawl 125 which is located on a shaft 125' and is moved towards said wheel by this shaft while a pull is exerted on the thread.

There is also a fiat spring 126. which bears against a side of the ratchet-wheel and'is affixed to the arm 120 of the lever 113 and the tension of which may be varied by means of an eccentric bolt 127 located in the lever 113.

'Referringnow to the form of cdnstruc tion illustrated in Figs. 8-10 the beaded .thread a: is drawn off the store or, supply bobbin 1 by a positively rocked thread guide 2, 3 and is conducted over a guide roller 4 which holds the threadalways in proper position with regard to the pre-dividing'mechanism. The thread-guide 2, 3 is shown in dotted lines also at 3 in its upper position. Below the thread guide 2 is an inclined guide gutter 5 for the beaded thread. This gutter at its upper end is exactly as broad as the bobbin 1, but its lower end is smaller in orderto conduct the thread securely-to the pre-dividing wheel 6. The beads present upon the thread are securely held-in the range of the wheel 6 by means of a guideplate 8, as well as by a little roll 7 which is attached to a lever 7" and is pressed by it with slight pressure against the wheel 6. s

The thread is then guided, from the wheel 6, over -two guides 9 and 28*, of which the first is positively rocked and the other is pressed by a spring 30 against an abutment 29, but yields easily to-"a'pull at the thread? The guide 9, 10 is shown also at 10' in dotted'lines in its lower position, and the guide 2 8 which is movably attached at 27 to a projection of the machine is shown in dotted lines also at 28 in its lower position.- These two thread guides co-operate in such a manner that the thread is lifted ofi? the yielding guide 28 during a part of the embroidering procedure so that the beads can pass beyond -it., The parts are arranged to act in such a way that the influence of the yielding thread guide will be removed just during the formation .of the loop so that this formation is not'ldisturbed. The thread passes from the guides just described to the needle 11 which is aflixed to the bar 32. w and m are two other positions of the thread a as resulting from= the other positions of the guides 9, 1O and'28 ,"vi a, those indicated in In order to transmit the rotary mo-.

which a spring 24 presses the wheel 6 in the 1 direction from 22 to 22 The wheel 6 is firmly connected with a ratchet-wheel 23 which is engaged by a pawl 21 if the wheel 6 is to bestopped. The pawl 21 is attached at 20 to a bell-crank lever 17/25, to the arm 17 of which is hinged the feeling or touching member 14 whichhas at its lower end a hook 15 extending through an aperture 13 of a rail 12 which is positivelymeciprocated.

in vertical direction by any suitable means. The size of the aperture 13 is such that the hook 15 may unimpededly pass through it and does not, therefore, at least in general, partake in the movements of the rail 12. The member 14 is subjected to the pull of a spring 26 connected at one end with this member and at the other end with the lever arm 25, the hook 15 being thereby, thus, kept away from the opposite rim of the aperture 13 of the rail 12. But the spring acts also in'the reverse direction, that is to say, it pulls the lever arm 25 towards the member 14, whereby the bell-crank lever 17/25 is so turned. that itsiarm 17 contacts with the abutment 18, in which position of the bellcrank lever the pawl'21 does not engage the ratchet-wheel 23.

The feeling or touching member 14 has at its lower end closeto the hook 15, a small plate 31 which co-operates with a countermember 33 aflixed to the needle-bar 32. The beaded thread passes through between the parts 31 and 33, and. when this latter is thrust forward on the next forward move- 'ment of the bar 32 with the member 33, the member 14 is turned and its hook 15 gets into a position in which it may be engaged by the rail 12- which then, on its next downward movement, pulls the member 14 downwards so as to make the pawl 21 engage the ratchet-wheel 23. The. pre-dividing wheel 6 is thereby stopped. If, however, no beads are present between the members 31 and 33, this latter does not and cannot move the former, in consequence of which the parts concerned remain in the position shown in Fig. 8. In other words: the wheel 6 is intermittently rotated and the embroidering procedure 1s continued in the normal way.
